On the basis of foreign research achievements, two kinds of domestic cold-formed steel sections are used as the parent materials to design Rosette-joints. Different styles of joint and various influencing factors (including form of hole, aperture, and the edge distance from the center of joint to the edge of the sheet) are taken into account, and four series of test specimens are schemed out. A series of axial-tension tests on all test specimens are carried out to investigate the shear strength of every rosette-joints.
